![]() at the corner between skins and hat (omega) stiffeners. It appears because of the difficulty to impose homogenous compaction pressure in regions of geometric complexity, e.g. The defect of interest in this study is the fiber waviness across the laminate thickness. It is essential to assess their impact on the strength and the stiffness of the structure. Defects are present in composites, mainly as a result of the manufacturing process. ![]() ![]() ![]() This presentation was made at the 2019 NAFEMS World Congress in Quebec CanadaĬomposite materials have been used for decades in the aerospace industry to design lightweight structures with high mechanical performances, i.e.
